Frequently Asked Questions

Upload a square PNG (256 × 256 or larger), choose the ICO sizes you need (16, 32, 48, 64, 128, 256), and download a multi-resolution .ico file ready to drop into the root of your website as favicon.ico — recognised by every browser since Internet Explorer 6.

usage

Windows desktop and shortcut icons traditionally include 16, 32, 48 and 256 pixel renditions in a single ICO so the OS can pick the right resolution per context. Modern Windows 11 prefers 256-pixel icons; older apps still need 32-pixel.

technical

Yes. Upload SVG (which scales cleanly at every resolution), JPEG or WebP and the converter rasterises each requested ICO size from the original. SVG produces the sharpest results because every size is rendered fresh from vectors.

features

Yes. Transparent PNG, SVG and WebP sources keep their alpha channel in the ICO, so the icon blends cleanly into dark and light browser tabs, Windows themes and macOS dock backgrounds.

features

favicon.ico is a multi-resolution Windows icon recognised by every browser. Apple touch icons are 180 × 180 PNG files referenced by an HTML link tag, used by iOS and iPadOS when adding the site to the home screen. Most modern sites ship both.

technical

No. Conversion runs entirely inside your browser, so your unreleased logo, beta product mark and confidential brand assets stay on your device.
